Change Details

Add endian.h. This includes sys/endian.h and then adds extra defines that glibc defines with double underscores for our _{BIG,BYTE,LITTLE,PDP}_ENDIAN macros. We also define __FLOAT_WORD_ORDER to be the same as _BYTE_ENDIAN since FreeBSD doesn't currently define this. This gives us good compatibility with Linux. There are some minor differences: o The extra glibc macros are not defined. These are all controlled with either __ at the start, or only defined when glibc is being built. o glibc only defines [bl]e*toh and hto[bl]e*() in permissive environments. FreeBSD always defines them (changing this likely requires multiple exp runs even though adding __BSD_VISIBLE guards is easy). o FreeBSD defines *enc() and *dec() functions always, but Linux never does. We choose to be permissive here since it's difficult to provide them for sources that include both (directly or indirectly). Sponsored by: Netflix

Enhance sys/endian.h to allow the FreeBSD specific *enc and *dec functions to be omitted and use that to omit these to be closer to glibc's implementatikon. Undefine bswap* macros. They aren't defined in glibc's implementation and at least mesa define these functions in an incompatable way. All this gives us good compatibility with Linux.
